Patented May 2, 1933 UNITED STATES PAT ENT; OFFICE y ROWLAND fr. WALEs,or NEW ROGHELLE, NEW -YoR-K Y r MOLD ron CONCRETE Application ledNovember 5 buckled to such an extent as to create large cracks betweenthe boards and provide a much deformed mold facing.

Among the objects of the invention are the following: (l) tosubstantially lessen o the weight of the panels; (2) to reduce thebending strains of the battens; (3) to provide a panel in which any partof the face thereof can be quickly and cheaply replaced if it becomesdamaged or deformed; (4) 5 to reduce the expansion and contraction ofsuch parts to a negligible amount, (5) to make such parts adaptable forthorough saturation with oil; and (6) to substantially cheapen the costsof such panels.

The foregoing and various other objects of the invention Which will bemade apparent as the description proceeds, I accomplish by making thepanels substantially entirely of wood, the face thereof being formed ofcom- 35 paratively thin boards mounted on battens,

and said panel being reinforced when mounted upon the supports or studsto form a mold, by reinforcing members which span the battens andco-operate with the locks on 0 the studs to hold the panels in placethere- 0 as viewed from the rear.

In the accompanying drawing Which- 12, A1925- .Serial N9. 68,598.

Fig. 4 is a horizontal section taken on the line l-l of Fig, 3. Y y

Referring to the drawing'let A indicate Va portion of a concrete wall orlstructure j formed Within a mold, the Ilia-jor POrton'f of which isprovided by panels B mounted upon supports or studs C fitted with tierods I) and locks E adapted for holding the panels in` place upon thesupports. The4 specific character of the studs C and 160 hereinillustrated are described in detail in my co-pending application SerialNo. M5,- '340, filed J une 6, 1921, which has Aeventi lated into PatentNo. 1925. Y s Y v`According to the present invention the panels B, whichare usually rectlglllu, in form, are, Preferably formed .Substantially.entirely of wood and consist of rigid frames n formed vbyhorizontalinembers Fand vertical members G. Laterallyispaccd within'ythe frame are rigid battens H, and the facing of the panel lisfprovidedby comparatively thin narrow boarding J of a thickness not eX- ceedingone-,half Yinch land a Width not eX- ccsd-ing two inches securedV in anypreferred manner to said frames and battens. Any of these boards J, itwill be appreciated, can be quickly and cheaply replaced if it everbecomes damaged from any cause whatever.

A panel so constructed, it Will be realized, will not have adequatelateral strength, but

this is supplied by reinforcing members K which are adapted to laterallyspan the battens I-I and co-operate with the locks E to hold the panelsin place upon the supports. In order that these reinforcing mem bers Kmay have maximum strength with minimum weight, I prefer to make them off ngle iron or the like. It is also preferable to form these membersseparately from the panel and have them adapted to be detachably hung onthe panel while it is being. hoisted to a high position.

For the purpose of preventing the top and bottom edges of the panelframe Afrom becoming injured through rough'usage I prefer to sheath saidedges with metal, as indicated at M. f

In use the panels B are first mounted upon 'l my name.

the supports or studs C behind the locks E. One leg of the angle iron Kis then slipped or positioned between the locks and the rear of thepanels and spanning the battens thereof, after which the locks E areoperated to clamp the member K in position. When thusly mounted theangle iron members K provide adequate reinforcement to maintain thepanel against transverse buckling. When dismantling the mold, the locksare opened, the members Kvwithdrawn, and the` panel thenwithdrawn fromthe supports.

From the foregoing description it Will be appreciated that the presentinvention accomplishes all of the objects enumerated,

andin addition thereto Will reduce the cost of constructing concretevWalls due to the savinginvtheginitial cost of such panels, and

in their upkeep, and further, because of their light Weight a Workmancan 'carry tWo panels Where at present he carries but one.

The invention, it is to be understood, may receive other vembodimentsfrom that herein specificallyI illustrated and describedWithoutdeparting from the spirit of the in- Y vention.

iWhatIclaim is: v y

A mold for concrete, comprising'supports, panels mounted between saidsupports, separate panel reinforcing members between the Asupports andextending transversely thereof, fand adjustable means cooperating Withthe supports for holding .the reinforcingV members against the panels,said reinforcing Y members each having apart overlying the adjustablemeans :and adapted to be supported thereby prior to pressure beingcreated between said mean-s and the panel. v, In witness whereof, I havehereunto signed ROWLAND T.
